摘要
An object of the present invention is to greatly reduce the calculation time in a numerical structure analysis apparatus based on the load transfer path method. The support point B of the structure to be analyzed is fixed, and parameters are set so that a load is applied to the specific load point A. Based on the entire stiffness matrix of the stiffness matrix holding means 1, the finite element method calculating means 2 calculates the deformation of the structure to be analyzed and obtains basic data such as the displacement amount of each point. The specific load point A and the support point B are fixed, three kinds of inspection loads are given to the change load point C, and each deformation is calculated by the finite element method calculation means 2 to obtain the displacement amount. The partial stiffness matrix calculation means 3 solves a multi-dimensional simultaneous linear equation based on the internal stiffness matrix, the load value, and the displacement amount of the structure to be analyzed, and obtains the partial stiffness matrix KAC. The stiffness index calculation means 8 calculates the value of the stiffness index U * from the partial stiffness matrix KAC and the displacement amount of the basic data. The change load point C is changed so as to sequentially follow all necessary points of the structure to be analyzed, and the value of U * at each point is calculated.
